Zoom Sucks

• Zoom abuses the installer flow on MacOS to bypass permissions dialogs (source)
• Zoom sends identifying device info to Facebook, even when users don't have a Facebook account (source) (fixed)
• A bug in Zoom sent identifying information (including email addresses and profile pictures) of thousands of users to strangers (source)
• Zoom claims that meetings are end-to-end encrypted in their white paper and marketing materials, but meetings are only encrypted in transit, and are available in plaintext to Zoom servers and employees. (source)
• zoomAutenticationTool can be used to escalat

Help my SSH keys are unavailable after restart

I'm still not sure what but on both my systems my keys just don't get loaded back into the ssh-agent on restarts and new login sessions. I got annoyed enough at it that I jumped through the hoops of putting ssh-add into a script and writting a property list file to load as a launchagent to fix it.

Add SSH Keys

If you haven't done so already you can use the well written gub hub instructions for generating ssh keys. Once you get them generated you'll add them with ssh-add -K <sshkey> where sshkey is the file path/name. Keys are stored by default in your ~/.ssh folder

Update

Note that you may need to use ssh-add --apple-use-keychain in Big Sur onward instead of ssh-add -K. I discovered the issue in Montery after skipping Big Sur.

Manual reloading SSH keys

The manual method (assuming your keys were stored into the Mac OS Keychain) is to open up Terminal

Installing tmux-256color for macOS

• macOS 10.15.5
• tmux 3.1b

macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):

If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

1. Play a song on your headphones
2. Option (⌥) click the Bluetooth button at the top of your screen
3. If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX

''' Script for downloading all GLUE data.

Note: for legal reasons, we are unable to host MRPC.
You can either use the version hosted by the SentEval team, which is already tokenized, 
or you can download the original data from (https://download.microsoft.com/download/D/4/6/D46FF87A-F6B9-4252-AA8B-3604ED519838/MSRParaphraseCorpus.msi) and extract the data from it manually.
For Windows users, you can run the .msi file. For Mac and Linux users, consider an external library such as 'cabextract' (see below for an example).
You should then rename and place specific files in a folder (see below for an example).

mkdir MRPC
